Abstract

Boron is one of the significant micronutrients for the plants; however, its excessive concentrations are lethal to plants. The accumulation of boron may cause damage to the liver, kidney, nervous system, respiratory system, digestive system, reproductive system and even threaten human life. Researchers consider using different methods to prepare boron chelating resins. In this work, two innovative, facile, and low‐cost methods were developed to prepare polystyrene-alcohol resins. The KDN and KLA resins had the highest adsorption capacity for boric acid in an aqueous solution at 288 K ,and the adsorption capacity was 36.17 mgand#183;g-1 and 43.47 mgand#183;g-1, respectively. The desorption percentages of boric acid on KDN and KLA resins were 90.75 % and 90.32 % respectively, by using 1 moland#183;L-1 HCl as an eluent. Therefore, KDN and KLA resins have the characteristics of a simple experimental process, large adsorption capacity, high elution rate, reusable, and low production cost. Therefore, it has a high commercial value and development prospects.

新型聚苯乙烯基树脂接枝曲氨醇和3-氨基-1,2-丙二醇对水和废水中硼的去除研究

硼是植物体内重要的微量元素之一;然而，其浓度过高对植物是致命的。硼的积累可能对肝脏、肾脏、神经系统、呼吸系统、消化系统、生殖系统造成损害，甚至威胁到人的生命。研究人员考虑使用不同的方法制备硼螯合树脂。在这项工作中，开发了两种创新、简便、低成本的方法来制备聚苯乙烯-醇树脂。KDN树脂和KLA树脂对硼酸在288 K水溶液中的吸附量最高，分别为36.17 mgand#183;g-1和43.47 mgand#183;g-1。以1 moland#183和L-1 HCl为洗脱液，硼酸在KDN和KLA树脂上的解吸率分别为90.75%和90.32%。因此，KDN和KLA树脂具有实验工艺简单、吸附容量大、洗脱率高、可重复使用、生产成本低等特点。因此，具有很高的商业价值和发展前景。
